Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional support structures are used in additive manufacturing, then the product can be manufactured with complex geometries, but the removal process requires precise drilling control and risks damaging the product
Solution Approach 1:
The support structure is segmented into a modular system comprising a support body, an intermediate layer, and a removal layer with distinct functions. The removal layer contains predefined removal zones that segment the removal process into controlled regions, allowing tool access without compromising the product integrity.
Solution Approach 2:
The intermediate layer acts as a mediator between the support body and the product surface. It provides a transition zone that facilitates tool access while protecting the product from direct tool contact, thereby preventing damage during the removal process.
2Ease of operation
If support structures are removed using traditional drilling methods, then the support can be eliminated, but the process requires precise control and increases labor effort
Solution Approach 1:
The removal layer is pre-configured during manufacturing with predefined removal zones and tool access paths. This preliminary action eliminates the need for complex real-time control during removal, allowing operators to simply follow the pre-designed removal paths and significantly reducing both time and effort.
Solution Approach 2:
The support structure's removal layer is designed to be self-guiding, where the predefined removal zones and tool access paths inherently guide the removal tool through the correct paths. This self-service design reduces the need for precise operator control and minimizes removal time.
3Productivity
If support structures are designed for easy removal, then the removal process is simplified, but the support structure complexity increases
Solution Approach 1:
The support structure is divided into functionally distinct segments: a support body for structural function, an intermediate layer for transition and protection, and a removal layer for facilitated elimination. This segmentation allows each part to be optimized independently, improving productivity without requiring the entire structure to be overly complex.
Solution Approach 2:
Different regions of the support structure are assigned different properties: the support body maintains high structural integrity, the intermediate layer provides protective characteristics, and the removal layer is designed with specific removal properties. This local differentiation enables easy removal while maintaining necessary structural functions, balancing productivity and complexity.
